What happens when a translation stop codon enters the A site of the ribosome? (please explain why and how)
What happens when a translation stop codon enters the A site of the ribosome? (please explain...
4) What happens when the ribosomal complex encounters a stop codon? Explain which, if any, tRNAs or proteins are involved 5)If the following DNA strand was used as a template, what would the sequence of an RNA be? 5́ GTACCGTC 3́ 6) How does acetylation of the chromatin affect the translation of genes contained within? In other words, does acetylation allow or inhibit transcription, and how?
k. Define: codon, anti-codon, transcription, translation, redundancy 1. Is it the case that a small change in DNA will always impact the protein? Explain. m. What mechanism is in place that ensures the right amino acid is added to the polypeptide? (Think codon-anticodon interaction) n. What happens if the tRNA enters the ribosome and the codon and anticodon do not match up?
During translation elongation, preloaded tRNA enters one of the sites of the ribosome. Which site is this?
When a stop codon is in place at the ribosomal A site, a ________________ factor binds to the site instead of a new aminoacyl-tRNA. List two specific causes of DNA mutations. One of the ways chromatin remodeling occurs to allow gene expression is ____________________ of ______________ residues of histones. During translation, elongation factors EF-Tu and EF-G use hydrolysis of the energy molecule ________ to successfully complete their tasks The __________________________________ sequence is a consensus sequence (in prokaryotic mRNAs only) that signals...
Place the events of Translation in bacteria into the correct order. The large ribosomal subunit associates with the small subunit and mRNA. The ribosome shifts along the mRNA in the 5' to 3' direction, moving the tRNA from the aminoacyl (A) site into the peptidyl (P) site The tRNA in the peptidyl (P) site shifts to the E site and leaves the ribosome. The next charged tRNA enters the open aminoacyl (A) site of the ribosome Aminoacyltransferase attaches the amino...
Place the following steps of TRANSLATION in the correct order for EUKARYOTES. The ribosome reaches a stop codon. A release factor binds and causes the release of the new polypeptide, along with the mRNA. The ribosome dissociates. v Acharged tRNA with a matching anticodon binds the mRNA codon in the A site. ✓ The ribosome moves exactly 3 nucleotides toward the 3* end of the mRNA. The small ribosomal subunit uses rRNA to bind to the Kozak sequence, which places...
